Unanswered: Remove the always white presence from left of the screen

Greetings! I've digg here and searched with Google but no luck. Here is my problem:

Whatever tests I made, with whatever components from Sencha Touch (1 and 2) I've got a white strip on the left of the screen, probably for scrollbar, even when is not needed. On browser (Chrome, on PC) there is no white band, only on smartphone. I thought is my smartphone guilty for that, but also the emulator from Eclipse show this white strip.
